4.33.1.3 Interior of discretized region

https://mathematica.stackexchange.com/questions/154544/interior-of-discretized-region

 
I have some domain of interest: 
 
r = 0.3; 
dom = ImplicitRegion[(x - 1/2)^2 + (y - 1/2)^2 >= r^2, {{x, 0, 1}, {y, 0, 1}}]; 
 
 
Now I can extract mesh of the whole domain or just boundary:

https://mathematica.stackexchange.com/questions/154481/listcontourplot-with-hatched-regions

 
I'm using ListContourPlot on a table of data, and I'd like to hash the regions rather than colour them, so the plot works in black and white. 
 
data = Flatten[Table[{x, y, Cos[x] + Cos[y]}, {x, 0, 3,  ...
